Why tiny atomic clocks may hold the key to China mass-producing cheap swarm drones

AI Summary

short article 1 min

A Chinese research team at Wuhan University, led by Professor Chen Jiehua, has developed a miniature atomic clock with potential implications for military technology. The clock, measuring only 2.3 cubic cm, is significantly smaller than existing US models while maintaining comparable performance, losing only one second every 30,000 years. Researchers claim this breakthrough could revolutionize drone warfare, underwater navigation, and battlefield communication by enabling more precise timing and coordination. The mass production of this compact and accurate clock could allow for cheaper and more effective drone swarms and other advanced military applications for China.
